SAFETY RAZOR.

Application filed January 27, 1927. Serial No. 163,865.

My invention relates to improvements in safety razors and is particularly applicable in the class of razors and blade stropping ineans in which the blade is rocked or ro.- tated for stropping its edge as the'device is reciprocated along the strop.` My invention is illustrated in connection with the class of razors known on the market as the Auto Stropsatety razor.

An object ot my invention is to provide a simple and improved form of blade holdcr in which the blade may be readily fitted and detached. y y i Another object of the invention is to provide improved means in a safety razor ior movably supporting a blade holder to cause the edge of a blade to rise from avstrop at the time that the reciprocating motions oi: the razor along the strop are reversed to prevent cutting` ol thestrop, and also to` retain the cutting edge of the blade in shaving.

relation to the guard. l My'invention comprises novel details ot improvement that will be more fully hereinafter set 'forth and then pointed out in the claims. Reference is to be had to the accompanying drawings forming a part hereo'flwherein Figl l is a partly broken plan view oi a safety razor embodying my invention;

Fig 2 is a partly sectional side view oi!V Fig. 3 is a substantially similar view, showing the parts in a different position;

Fig, 4; is a detail cross section;

Fig. 5 is a plan view illustrating the parts in position for inserting or removing a blade; l

Fig. 6 is a longitudinal sectional -view ot the razor;

Fig. 7 is a detail section;

Fig. 8 is a detail perspective View of aretainer, and i Fig. 9 is a side view illustrating a 1nodi` cation. i

Similar numerals of reference indicate corresponding parts in the several views.

The numerals l indicates a base or frame shown provided with. a guard 2 for a blade 3. The guard may be in ordinary comb like torni, as illustrated. A handle is indicated at et which may be detachably connected with frame 1 as by screw threads at 5. At 6 is indicated a blade holder, shown in the formel a substantially iiat plate, upon which the blade 3 may rest with its cutting` edge projecting in` position to cooperate with the guard ior shaving. The blade holder or plate 6 is provided with means for positioning the blade thereon and for clamping them together shown arranged as `follows: an arm or latch 7 is pivotally supported upon holder or plate 6 by means of a rivet 8 so as to swing edgewise respecting the holder. The arm or latch 7 is provided with a jaw or recessed portion at 7a near its free end adapted to receive the edges o t the blade 3 and the holder `or plate 6 therebetween to retain said parts clamped together. An arm or latch 7 shown at opposite ends of'holder or plate 6, near the inner portions of the latter, to correspond` ingly clamp and retain the end portions oi the blade. The holder or plate `6 is shown provided with projections 6L`adapted to enter apertures oropenings 3 in the blade to retain t-he blade in shaving position on the holder. Said apertures or openings may be stamped through or embossed in the material of the blade and the projections 6 may be formed by embossing or pressing the metal' oi' the holder. I have illust-rated aperturcs 3 in the blade in the form oi' a trade niark, name or symbol, such as Valet, and the projections GfL are located in such relation to the tradeimark or symbol apertures or impressions 3Lnu that when the `blade laid upon the holder or plate G `certain et the apertures a ot diii'erent letters will be in position to receive-certain projections 6, whereby when the bladejand the holder are clamped together theblade will be prevented from sliding along the holder and will be retained in desired position. The fea-ture described of utilizing a trade-mark, name or symbol on one part in cooperation with pro ject-ions on another part, such as in the blade and holder, are set forth in my application filed 1J une 24.-, 1924., Serial N o. 721,972. When the projections (5EL are in therapertures or impressions 3 of theblade and the jaws of the arms or latches 7 are closed against said parts the blade willbe retained in shaving position on the holder, (Fig. l). To release the blade it will merely be necessary to swing the arms or latches outwardly, as in' blade.

In the example illustrated the blade holderis pivotally supportedfby a frame 9 which is shown provided with a base portion 9a extending over the base or frame 1 and .with spaced arms 9b between which the blade holder iis'pivoted. The blade holder is shown provided with ears 6b, which may be ystamped from the 'metal of the holder plate and bent substantially at right angles there- 'toto fit adjacent to the arms`9, (Figli), rto'which arms said ears are pivoted by means of pivots at 10, 10a. The pivots have shoul- -ders and heads by which they are secured to the ears and the pivots are journaled in the arms 9a. The frame 9 1s pivotally conr nected 'with trame 1 by means of pivots 11 whichare shown located in outwardly disposed arms or proJections 1a shown extending from base 1 atfsubstantially right angles thereto, (Fig. 6), whereby frame 9 may rock relatively to frame 1. The frame 9 isprovided with a shaft or roller12 adapted to lengage a strop A for rotating the shaft,

which shattfisr provided with a gear 13 in mesh' withgear 14 that-is secured to or carried kby the pivot 10, whereby the holder 6 may be rocked-for stroppingthe blade edge when the razor is mounted on the strop and `is reciprocatedalong thelatterrfor rotating Y the shaft 12, (Fig. 4).

The shaft or. roller 12 is shown comprising a tube 12a receiving .shaft-s 12", 12c which are secured to the tube, as by denting portions 12d of.v the tube ,l into recesses in the shafts, whereby said parts are rotatively united and are kept from endwise .displacement `relatively to each other.

(Figi. 6). n

' The frame-1 is provided with one or more n retainers 15, preferably one at each end of the guard, shown in hook-likeform adapted to retainthe holder with the blade in shaving relation to the guard. The arms or latches 7 are shown provided with outward- .Y ly pro]'ect1ng portions 7", 1n recess form,

adapted to'receivethe corresponding retain- Y er 15, (Fig. 2), to retainthe holder and blade in shaving relation to theguard. The guard K portion offrame 1 Yis shown provided with openings 15", (Fig. 5),.adapted :to receive .the proJecting portions 7" of the arms or latches 7 to permit engagement ofthe retainers V15 therewith, (Fig. 2). Since the frame-9 will" rock respecting frame 1 the blade holder may be connected to the frame 1in shaving relation,.b v tilting frame 9 to lthe. right,yas indicated in Fig. 3,.placing i thewbladel inposition upon the guard and ,pushing frameV 9 to the left in Fig. 2 to cause the retainers 15 to enter the recessed projecting portions 7 b of the arms orlatehes 7, and the reverse opera-tions may be effect- `retainers 15, as indicated in Fig. 9. In

such form the frame 9 may be moved to the right hand in Fig. 9 to release holder 6 from retainers 15 and may be pushed toward the'lett in said figure to engage said parts. The guard may have stops 2 at the corners of the blade, (Fig. 9).

Means are provided to retain the blade in shaving relation to the guard, or in other words to keep the retainers 15 in cooperation with the projecting portions 7 b of the latches 7 or with the holder 6 for shaving purposes. In the example illustrated a retainer member 16, shown in the form ot a sleeve or tube, is slidably mounted upon the reduced portion il of handle 4 adapted to rest against a shoulder or stop 4" thereon, (Fig. 3), the member or sleeve 16 being shown provided with a projection or finger 16n slidable through an opening 1'; in frame or base 1, (Fig. 4C), to be located behind shaft or roller 12 to retain the frame 9 and thereb. the bladel holder or plate 6 so that the atter will be retained by the retainers 15 with the blade in shaving relation to the guard for shaving. A finger piece or seat 16b on member 16 permits ready sliding of the latter along the handle. The member 16 is shown provided with a spring-acting stop 16, which may be stamped from the metal of the sleeve and has an inward springr tendency adapted to slide along an inwardly tapering portion 4C of handle 4 to engage a stop shoulder 1d on the handle to limit the outward movement of sleeve 16 when its projection or finger 16n is engaged with shaft or roller 12, (Fig. 2), and to keep the sleeve from falling from the handle when the lutter is removed from frame or base 1.

)Vlien the parts are in shaving position, (Figs. 1 and 2), and it is desired to strop the edge `of the blade the sleeve 16 will be slid to move its projection 16 away from shaft or roller 12 and then the strop will be pushed through the razor under said shaft or roller for stropping, (Fig. 4). When the razor is moved along the stro as to the left in Fig. 4, the cutting edge o the blade will drag on the strop for stropping it. lVhen the razor is first moved in a reverse direc-v lll) ing action taking place each tiine the direction of sliding the razor along the strop is reversed.
